IN-VENTOR paul C11 Hykes YY 'R "m E I wwf u E amm ATTORNEY United StatesPal-fmt@ This invention relates to wheel attaching means and has for anobject the provision of improvements in this art. l

One of the particular objects of the invention is lto e provide wheelattaching means which furnishesl an extremely strong and reliableattachment to the hub. f

Another object is to provide very accurate piloting and securement ofparts.

' Another object is to provide attaching means which is adapted for usewith both front and rear wheels and with both single and dual wheels.

In'fFig.`4the-shorter clampingboltffor the' front is .indicated-l bythe reference numeral 13?.

Ifonlyv 'a single disk is secured onthe hub, as shown in Figs. 3 and 4,the surrounding flat-faced flange 27`of the clamp vnuts engages the atface of the disk outside the conical opposite or back-side depression23.

Another object is to provide wheel attaching means inA which theattaching pressure is` applied at a distance Fig, 1 is an outside or endelevation of a wheel-hub assembly provided with securementarrangements-jembodying the present invention; y v

Fig. 2 is an enlarged section through a single connec-v tion, as on thekline 2-2of Fig. 1; l

Fig. 3 is a section like Fig. 2 but "showing a single disk secured tothe hub; and

Fig. 4 is a section like Fig. 3 but showing partsbuilt for single disksecurement.

The attaching means is employed with one or more wheel disks 10 eachcarrying at the outer periphery a rim 11 for mounting a tire.

The disk or disks are mounted on a wheel hub 12 provided with aplurality of clamping bolts 13 (six as'` shown) staked or otherwisetightly secured in the ange 14 of the hub.

At each bolt location the hub yflange around the bolt holes is providedwith conically countersunk portions 15 which are inwardly relieved at16.

The disks 10 are provided with'fho'les 20 corresponding in number andlocation to the clamping bolts 13, and at yeach hole there is provided aconical annular boss 21 terminating in a reverselyfconical.countersunkportion 22. On the sideopposite the conical bosses 21 thereare corresponding conical depressions or'recesses 23.

Clamping nuts 25 are providedk for threading on the clamp bolts 13 tosecure the wheel disks to the hub ange. The nuts are formed with aninner conical piloting projection 26 and an outer vprojecting.circumferential clamping flange projection 27. YAn annular groove 28 isformed between the innerconical piloting projection 26 and the outerclamping projection 27. The hole in the nut is relieved `Ainteriorly byan enlargement 29 .of greater diameter to lclear the threads on thebolts to prevent injury to the threads.

The attaching means is uniformly applicable for secur- When twoAwheelslare secured on rthe hub, as shown in Fig. 2, the bosses of theouter wheel disk are all faced outwardly and the conical inner portion26 of the nuts enters the conical recess 22 and thereby the nuts' pilotthe disk into accurate position. Then the outer `)flanges 27 of the nutsengage the flat face ofthe disc outside the conical bosses 21 andtightly secure the disk -to the hub. The grooves 28 lof the nuts spanand clear the bosses 2'1 of the wheel disk. e

Very extensive laboratory and road tests have shown that the presentattaching construction gives very accurate and strong securement ofwheels to hubs. Whereas, with previous wheels the lfailures occured atthe hub connection, with the present arrangement the hub connectionproved so strong that failures occurred at the lightening or hand holes31 of the disk. When these holes were made smaller to strengthen thedisk a much higher load could be applied. Y

It is thus seen that the invention provides a new combination ofelements which as a whole produces a very superior attachment of wheelsto hubs. While the elements are known separately they have never beencombined in themanner illustrated, so far as known, to

give the improved results realized by the present invention. Withal, theconstruction is very simple and inexpensive and uses the same essentialparts for allv wheels, front or rear, single or dual.

While oneembodiment has beendescribed for-pur- .posesof illustration,vitis to be understood that there may be various embodiments landmodications Vwithin the scope of the invention. Y

What is claimed:

1. Wheel attaching means comprising in combination,

a hub provided with an. annular flange, a plurality of clamping boltssecured in spaced holes in said ange, the holes having conical recessesvaround said bolts, a wheel disk provided with oversize holes to receivesaid bolts, conical bosses formed of full-thickness bent portions ofsaid disk disposed around said disk holes :fitting in the conicalrecesses of the hub llange to pilotthe disk into proper position, thedisk'having conical concavities opposite the bosses and reverselydirected conical concav-l -ities within said bosses, and clamp nutsthreaded on said bolts, said clamp nuts having an innerconical pilotingVprojection and an outer lannular clampingl projection with an annulargroove between, the outer clamping prosuicient to freely receive saidboss.

2. Wheelattacl'iing means` comprising incornbination,

` a hub provided with an annular ilange, a plurality of 2,925,304".Yrape-ai Fel 16 1260,

size holes in said disk receiving said bolts, a conical..

boss formed of a full-thickness bent portion of said disk disposedaround each hole fitting in a recess in the flange,

all bosses of the disk being disposed on Ya common side` tion standingat a distance outside said bosses to engage a at surface of the seconddisk, and an intermediate an nularrecess spanning the boss, said annulargroove being of a depth and width sucient to freely receive said boss.
